Reconstructing monsoon variability during the Late Holocene at Ia Bang Lake, Central Highlands of Vietnam
Vietnam is highly sensitive to ongoing climate change, with variations in monsoon intensity exerting significant socio-ecological impacts. However, paleoclimate reconstructions from Central Vietnam remain scarce and have predominantly focused on the Central Highlands. This study presents a 4500-year sediment record from Ia Bang Lake (IAB), combining sedimentological (grain-size) and geochemical (XRF) analyses to reconstruct Late-Holocene hydrocli…
Social resilience to changes in climate over the past 5000 years
Increasing numbers of studies are investigating the phenomenon of social resistance, particularly instances of stability or prosperity in the face of climatic–environmental stresses over a long period. This emerging research field of climate resilience explores the capability of socio-ecological systems to cope with stresses, maintain functions, and evolve into more desirable systems within stressful climatic and environmental conditions. This sy…
Mineral dust and lead deposition from land use and metallurgy in a 4800-year-old peat record from the Central Alps (Tyrol, Austria)
Humans have occupied the Alps over most of the Holocene. Yet, continuous records on the impact of using montane resources and landscapes are scarce or confined to segregated areas or periods. We present a high-resolution geochemical record of the last 4800 years from the ombrotrophic peatland Piller Moor in the Central Alps (Tyrolean Oberland, western Austria), using inductively coupled mass plasma spectrometry (ICP-MS) and highly efficient inter…
Diatom-based indications of an environmental regime shift and droughts associated with seasonal monsoons during the Holocene in Biển Hồ maar lake, the Central Highlands, Vietnam
The interactions of the different monsoon systems across Southeast Asia create extreme climate phenomena. Central Vietnam, located near the centre of this transitional region, has encountered numerous effects. As a result, its sediments from lakes or speleothems are valuable archives for interpreting past climate variability. However, there is still a lack of high-resolution paleoenvironmental and palaeoclimatic reconstructions during the Holocen…
Environmental history recorded over the last 70 years in Biển Hồ maar sediment, Central Highlands of Vietnam
A high-resolution, 1250-year long drought record from Ea Tyn Lake, Central Highlands of Việt Nam
An understanding of past climatic variability at regional to local scales is mandatory for a proper evaluation of current and potential future repercussions from global climate change. The Southeast Asian tropics remain severely under-represented in paleoenvironmental and paleoclimatic reconstructions, although a few recent paleoclimate studies evaluated the variability, position and strength of the main Asian monsoon systems at different timesca…
Land use patterns and climate change—a modeled scenario of the Late Bronze Age in Southern Greece
In this study, we present a modeling approach that investigates how much cultivable land was required to supply a society and whether societies were in need when environmental conditions deteriorated. The approach is implemented for the North-Eastern Peloponnese and is based upon the location of Late Helladic IIIB (1300–1200 BCE) archaeological sites, an assessment of their sizes, and a proposed diet of the people. Based on these information, the…
Steady transformation of primeval forest into subalpine pasture during the Late Neolithic to Early Bronze Age (2300−1700 BC) in the Silvretta Alps, Switzerland
The question of the origin of Alpine farming and pastoral activities associated with seasonal vertical transhumance and dairy production in the Silvretta Alps (Eastern Switzerland) has recently benefitted from renewed interest. There, pastoral practises began during the Late Neolithic (2300 BC), but alpine dairy farming was directly evidenced so far only since the Late Bronze Age/Early Iron Age (1300–500 BC). The vegetation development, timberlin…
Late-Holocene coastal depositional environments and climate changes in the Gulf of Corinth, Greece
Multidisciplinary studies in coastal systems of the eastern Mediterranean region have proven to be excellent tools in understanding paleoenvironmental, paleoecological, and paleoclimatic changes that took place during the Holocene period, and how these changes interacted with urban development and growth. This paper presents sedimentological, high-resolution x-ray fluorescence (XRF scanning), micropaleontological, and x-ray diffraction (XRD) data…
Vegetation responses to the last glacial and early Holocene environmental changes in the northern Leizhou Peninsula, south China
A well-dated palynological record spanning the interval ~ 40,500–7060 cal yr BP, retrieved from a peatland on the Leizhou Peninsula in south China, clearly shows regional vegetation and climate changes during the last glacial period. Pollen data showed that the study region was mainly covered by subtropical evergreen trees during Marine Isotope Stage 3 (MIS 3), indicating a subtropical climate with relatively high temperature and precipitation. D…
Natural and human induced environmental changes preserved in a Holocene sediment sequence from the Etoliko Lagoon, Greece
Late Glacial to mid-Holocene palaeoclimate development of Southern Greece inferred from the sediment sequence of Lake Stymphalia (NE-Peloponnese)
Tracking Heracles - Environmental change on the Northern Peloponnesus driven by climate and culture
A comprehensive numerical chronology for the pre-Columbian cultures of the Palpa valleys, south coast of Peru
Molluscs as Evidence for a Late Pleistocene and Early Holocene Humid Period in the Southern Coastal Desert of Peru (14.5°S)
The southern Peruvian coastal desert around Palpa, southern Peru (14.5°S) is currently characterized by hyper-arid conditions. However, the presence of two species of molluscs ( Scutalus , Pupoides ) and desert-loess deposits indicates the past development of semi-desert and grassland ecosystems caused by a displacement of the eastern desert margin due to hydrological changes. Radiocarbon dating shows that the transition to a semi-arid climate in…
Dating methods and geomorphic evidence of palaeoenvironmental changes at the eastern margin of the South Peruvian coastal desert (14°30′S) before and during the Little Ice Age
A Chronology of the Pre-Columbian Paracas and Nasca Cultures in South Peru Based on AMS 14 C Dating
The people of the Paracas and Nasca cultures, the creators of the famous geoglyphs, lived in the desert of the southern coast of Peru between about 800 BC and AD 650. The archaeological chronology of these cultures has been based almost exclusively on a sequence of ceramic styles. The absolute dating of some of the style phases was supported by a few radiocarbon dates (Rowe 1967). Here, we present an absolute chronology of the Paracas and Nasca c…
Geoarchaeological Evidence From Desert Loess in the Nazca–palpa Region, Southern Peru
The paper presents proxies from an interdisciplinary geoarchaeological working group. Sediment analyses and geomorphological studies, radiocarbon ages of snail shells and luminescence dating of loess allow a preliminary chronology of the environmental evolution of the eastern Atacama desert, Nazca–Palpa region (southern Peru). Until now, typical desert loess was unknown from the arid western flank of the Andes (southern Peru). The loess points to…
